Hair brush

Abstract

A snap-together, two piece, injection molded hairbrush includes a brush body and a bristle insert. The brush body includes a head and a handle. The head has a first and second end and a first and second side. The first and second ends and first and second sides form an open frame and a plurality of ribs extend between the first and second ends to define a first set of air slots. The handle has first and second ends and the first end of the handle is attached to the second end of the head. The bristle insert includes an open frame, a plurality of convex webs, a plurality of spaced bristles, and a connector. The open frame has first and second sides and first and second ends. The plurality of convex webs extend between the first and second sides of the open frame and are spaced from one another to define a second set of air slots. The plurality of spaced bristles are carried on each of the webs and extend outward from the webs. The connector mates with the frame of the head to connect the bristle insert to the head.

What is claimed is: 
     
       1. A hairbrush comprising: a brush body which includes: a head having first and second ends and first and second sides which form an open frame and a plurality of ribs which extend between the first and second ends to define a first set of air slots; and   a handle having first and second ends with the first end of the grip attached to the second end of the head; and     a bristle insert which includes: an open frame with first and second sides and first and second ends;   a plurality of convex webs extending directly and without intersection between the first and second sides of the open frame, the webs being spaced from one another to define a second set of air slots, the second set of air slots extending directly and without interruption between the first and second sides of the open frame;   a plurality of spaced bristles carried on each of the webs, the bristles extending outward from the webs; and   a connector for mating with the frame of the head to connect the bristle insert to the head.     
     
     
       2. The apparatus of claim 1 wherein the handle is narrower than the head. 
     
     
       3. The apparatus of claim 1 wherein the brush body and bristle insert are each one piece injection molded. 
     
     
       4. The apparatus of claim 3 wherein the brush body and bristle insert are each one piece injection molded with a polypropylene-containing material. 
     
     
       5. The apparatus of claim 1 wherein the webs contain holes between the adjacent bristles. 
     
     
       6. The apparatus of claim 1 wherein the bristles are configured such that they do not form a straight line from the first side to the second side of the head. 
     
     
       7. The apparatus of claim 1 wherein the bristles extend outward from the webs at various angles with respect to the webs. 
     
     
       8. A hair brush comprising: a one-piece injection-molded brush body comprising a head and a handle; and   a one-piece injection-molded bristle insert comprising: a webbed portion which alternates web strips with spaces, the spaces continuing without interruption from a first side of the bristle insert to a second side of the bristle insert opposite the first side;   a plurality of bristles extending upward at various angles from the web strips in the webbed portion; and     snap connection means running along side the webbed portion for connecting the bristle insert to the head.   
     
     
       9. A hairbrush comprising: a head having alternating ribs with open spaces;   a handle connected to the head for holding the hairbrush; and   an insert for connection with the head with a plurality of convex webs alternating with open spaces and a plurality of bristles carried on the webs, the convex webs extending uninterrupted from one side of the insert to an opposite side of the insert and the open spaces likewise extending uninterrupted from one side of the insert to an opposite side of the insert.   
     
     
       10. The apparatus of claim 9 wherein the head and the handle are one piece, injection-molded, and made with a polymeric material. 
     
     
       11. The apparatus of claim 10 wherein the polymeric material includes polypropylene. 
     
     
       12. The apparatus of claim 9 wherein the insert is injection-molded with a polymeric material. 
     
     
       13. The apparatus of claim 12 wherein the polymeric material includes polypropylene.
